There are things in place now to stop medics being bias and it still happens. There are current and ex Search and Resuce and above who I've experienced being biased. It's not even always conscious bias that can cause it (supporting gang/friends etc), it's also unconscious bias because of past situations. You see this with APD, too.
You choose to play the "pacifist" faction, I don't see the need to arm medics. If you feel the need to have weapons, work with APD to create a more symbiotic relationship.
